Why Faces of Other Races Look Alike |The Brain, Memorizing & Remembering Faces | LiveScience



The brain works differently when memorizing the face of a person from one's own race than when attempting to remember the face of someone of another race, new biological evidence suggests.

The well-documented "other-race effect" finds that people are less likely to remember a face from a racial group different from their own. Northwestern University researchers set out to determine what causes this rift in perception and memory by using electroencephalogram (EEG) recordings, which measure brain activity, while participants viewed photos of various faces.

The researchers found that brain activity increases in the very first 200 to 250 milliseconds when seeing both same-race and other-race faces. Previous research has associated this very early phase, known as the N200 brain potential, with the perceptual process of individuation. That process involves making out the unique facial features of each person, such as the shape of their eyes and nose.
